Abstract: A flexible tube insertion support apparatus includes a generation section configured to generate propriety information regarding a propriety of a twisting operation of a flexible tube in accordance with a force quantity of an external force applied to the flexible tube when the flexible tube is twisted in a counterclockwise direction or a clockwise direction around a central axis of the flexible tube. The external force is detected by at least one external force detector that is disposed on the flexible tube to be inserted into the subject and configured to detect the external force. The flexible tube insertion support apparatus also includes an output section configured to output the propriety information generated by the generation section.
